.510 DTC EUROP

The .510 DTC EUROP is a French riflecartridge developed by Eric Danis in order to comply with firearms legislation in Europe which regulates .50 BMG rifles. In response to the .50 Caliber BMG Regulation Act of 2004, which banned future sales of .50 BMG shoulder-fired rifles in California, long-range shooters in that state have begun to adopt this cartridge as a manner following the new legislation.

The .510 DTC EUROP uses the same bullet as the .50 BMG, but has slightly different case dimensions. The case is 0.1 inches (2.54 millimeters) shorter and uses a steeper shoulder than standard .50 BMG ammunition. .510 DTC EUROP cases can be made by shortening and then fire-forming .50 BMG cases. The new round has almost identical ballistics, but because of the different dimensions, rifles chambered for the .50 BMG cannot safely fire the .510 DTC EUROP, and vice versa, and therefore do not fall under the same legal prohibitions. .510 DTC EUROP rifles, like .50 BMG rifles outside California, are simply standard modern rifles and can be purchased as such.
